Hi,

I would suggest to use http://www.cacert.at/random/ to test the randomness of the DNS source ports. Due to the large variety of random-number sources that have been tested there already, it's useful as a classification service of unknown randomly looking numbers. You just have to collect 12 MB of numbers from a DNS server and upload it there. (If you get 2 Bytes per request, that's 6 million requests you have to do)

I don't see the point of evaluating the quality of a random number
generator by statistical tests.

We successfully used statistical tests to detect broken random number generators, we informed the vendors and they fixed them.

Best regards,
